How to make the Uncrustable-style sandwich without nesting cookie cutters or a sandwich cutter:1.) Make your sandwich as usual.2.) Find two ramekins, custard cups, teacups, or whatever you have with one just slightly larger than the other.3.) Use the smaller one to press the sandwich closed (as if using a cookie cutter, but don't push all the way through or twist).4.) Finally, use the larger one to press down even harder, and then trim around it with a paring knife.
